In Great Britain Februaryzl, 1948" 1 Claim. (01. 36-195) Thisapplication is a continuation as to all common subject-matter of my copending application Serial No. 784,453 filed November 6, 1947,w'hich hasmatured into Patent No. 2,526,- 925 granted October 24, 1950.

Although principally intended fonapplication to ladies 'fashion shoes,the invention is by no means limited in this respect. Accordingly, forthesake of convenience inth'e following further description the termsh'oe will be used in a generic sense to include any footwear towhichthe invention may with advantage be applied.

According to the invention described in the said co-pending applicationthere is provided a lastedshoe wherein there is a flap and associatedfilling material, the said flap being attached to the lower portion ofthe upper, folded over the fillingmaterial to locate thesame betweenitand the upper, and turned inwards and secured beneath the insole,contiguou'slywith the upper, suchwise as to provide'around the shoe anup standing protuberantformation having the appearance of or resemblinga platform.

The flap will, for convenience, be hereinafter referred to as theplatform fla p.

As previously stated, the iriven titi'n described in the parentspecification was confined to lasted shoes, that is tosay shoes of thekind having an upper which is lasted to an insol'e. ape aim of thepresentinvention, on the other 'hand,is to apply a platform' flap to aslip-lasted shoe by which term is meant' a shoein which a relativelythin layer (hereinafter for conveniencereferred to, where the context soadmits, as a -sock or equivalent) and an uppe'rare stitched'together toproduce, without a normal lasting operation, an upper component minus aninsole proper of conventional thickness.

According to the present invention, then, the 'upper'of aslip-lastedshoe has' attached to its lower edge a platform flap which.is turned over and secured either directly beneath the sock orequivalent, or beneath a filler ordummy innersole applied to theunderside of said sock or equivalent.

The upper and the platform flap may conveniently be together machined tothe sock or equivalent by plain seaming.

As in the invention described in the parent specification, the spacebetween theupper and the attached. platform flap is filled or packed outwith any suitable filling material; such, for instance, as cork, leatheror felt, serving to en phasise the platform icrmation and impart theretothe appearance of a flange projecting upwards from the outersole of theshoe on the heel 4.

2 exterior of the upper. The filling 'mate'rialmay be of strip form, andthe cross-sectional shape of the strip may vary to impart differentshapes to the platform formation. For example, the filling strip may betubular.

The outersole may be of leather or rubber, e. g. crepe, stuck on byadhesive.

The filler or dummy innersole, when provided, may be of rubber, felt,leather o'rany other suitable material.

The term upper is used in this specification and in the appended claimsin its widest sense to include not only an upper which extendscontinuously right around the shoe, but also an upper with separatedparts, or having one or more portions thereof omitted, suchwise as toleave an opening or openings at the toe or/and the heel or/and at thesides as, for example, in a shoe of the sandal'type.

The invention also'inc'ludes a method of manufac'ture of the improvedslip-lasted shoe as will be hereinafter described.

In order that the 'in'ventionmay be nio'reclearly understood and readilycarried into practical effect, a specific constructional example of theimproved shoe, and the preferred method of making the same will now bedescribed with referenceto the accompanying drawings, wherein:

Figure 1 is a longitudinalsectional view of so much of the said shoe asis necessary to illustrate the invention.

Figure 2 is a detail fragmentary perspective view illustrating themanner in which the upper, the platform flap and associated fillingmaterial, the sock and the dummy innersole are correlated and assembled,

Figure 3 is a detail sectional view, drawn to an enlarged scale, of theheel end "of the shoe,

Figures 4-l0 are detail sectional views illustrating the successivestages in the manufacture of the shoe, and

Figure 11 is 'a view similar to Figure 8 showing a modification.

Like parts are designated by similar reference characters throughout thedrawings.

The shoe illustrated in Figure 1 is of the"sliplasted 'typeincluding athin sock I of, say, textile material and an upper '2 which are stitchedtogether by a single lineof stitching 3 to produce, without a normallasting operation, an 'upper component minus an insole of conventionalthickness. The sock l extends through the forepart only of the shoe,"its rear end being secured beneath the forward end of a, built-upinternal In accordance with the characteristic feature of the presentinvention, the upper 2 has attached to its lower edge, by theaforementioned line of stitching 3 and also by a further line ofstitching inserted higher up and parallel there to, a, platform flap 6which is folded over an applied strip 1 of filling material and turnedinwards and secured beneath a dummy forepart innersole 8, e. g. ofrubber, stuck by adhesive to the underside of the sock I. As shown moreclearly in Figure 2, the sock I, the dummy innersole 8 and the inturnedportion lia of the platform flap 6 are secured together around theforepart of the shoe, by a vertical lockstitch seam 9 spaced somedistance inwardly from the line of stitching 3. As a consequence of thesock I, the upper 2, and the platform flap 6 being seamed togetheraround the forepart of the shoe by the line of stitching 3 there isproduced a peripheral rib which projects down from the underside of thesaid sock. Within the confines of this peripheral rib there isaccordingly a shallow cavity which, however, is filled in by the dummyinnersole 8. The strip 1 of filling material, which is completelyembraced by the platform flap 5, serves to emphasise and enhance theresulting protuberant formation F which has the appearance of orresembles a platform. The formation F, moreover, is flange-like andprojects upwards from the outer sole ID of the shoe on the exterior ofthe upper. The outer sole If! is stuck directly to the inturned portion6a of the platform flap 6 and to the undersides both of the forepartdummy innersole 8 and of the lower of two inserted pieces II and H uponwhich the internal heel 4 is secured.

As will be understood, the particular construction with which theinvention is concerned is, in the illustrated example, thereforeconfined to the forepart only of the shoe where, it will be noted, theupper 2 is not turned inwards and lasted to an insole, contiguously withthe inturned portion 5a of the platform flap 6; it is in this importantrespect that the slip-lasted shoe constituting the present inventiondiffers from the lasted shoe described in the parent specificationaforesaid.

Nevertheless, the protuberant formation F extends right around the shoe,the inturned portion 6a of the platform fiap 6, at the heel end, beingsecured beneath the upper 2 and a conventional heel stiffener l2. Theinturned portions 2a and 2b of the two layers of upper materialenclosing the heel stiffener l2 are tacked to the underside of theinternal heel 4 by tacks such as l3 (see Figure 3). The precise form,and the manner of incorporation, of the internal heel 4 constitute nopart of this invention: sufiice it to say that the said heel which, inthe specific example illustrated in Figure 1, includes a tapered layer Mof cork and a superimposed tapered pad l5 of sponge rubber overlaid by aheel seat layer it, may, during manufacture of the shoe, be applied tothe bottom of the last so that it becomes automatically incorporatedduring lasting of the heel part of the upper. Alternatively, a dummyheel may be applied to the last so as to enable an upper with asufficiently deep quarter or counter for the accommodation of aninternal heel or an elevator to be produced, in which instance the heelor elevator would be inserted into and secured within the upper afterremoval of the last therefrom.

The shoe may be completed by the incorporation of an additional fulllength sock l1 disposed to overlie the sock l and the heel seat layerIii. A heel lift is may be applied to the underside of the outer soleHi. i

The characteristic steps, so far as the present invention is concerned,in the manufacture of the herein described slip-lasted shoe will now bebriefly described with reference to Figures 4 to 10.

First, the sock and the parts to form the upper are cut out or clicked,and the upper is fabricated. Next, a comparatively wide band of suitablematerial, initially arranged inside out, to provide the platform flap,is accurately placed upon and attached right around the upper 2 by thesingle line of stitching 5 spaced from and extending parallel to thelower edges of the upper and the flap (see Figure 4). At the next stageillustrated in Figure 5, the peripheral edge of the sock l is accuratelyregistered with and then seamed to the lower edges of the upper 2 r andthe platform fiap 6, care being taken to en sure the rib R resultingfrom such seaming projects beneath the sock l instead of extendingoutwardly at an angle. Into the upper component thus produced is thenslipped or forced a last I9 to fill out the upper 2 and impart theretoshape and solidarity, whereupon the strip a of filling material is stuckinto position on the marginal edge portion of the platform flap 6 asdepicted in Figure 6. The shallow cavity C produced within the confinesof the rib R is next filled by sticking the dummy innersole 8 upon thebottom of the sock I (Figure 7). At the stage depicted in Figure 8, theplatform flap 6 is folded over the filling strip 1, the then freemarginal portion 6a of the fiap being turned inwards and secured, bysticking, beneath the dummy innersole 8. Incidentally, there is nodirect connection between the dummy innersole and the upper 2. The lastI9 is subsequently removed and the sock l, the dummy innersole 8 and theinturned portion 6a of the platform flap are additionally united, asshown in Figure 9, by a vertical lockstitch seam 9. This step is not,however, essential. The characteristic construction is completed by theapplication of the outer sole It, which is stuck on, and by theincorporation, if desired, of an additional sock I! (Figure 10).

In the modification depicted in Figure 11, the dummy innersole isomitted, the portion 6a of the platform flap 6 being in this instancesecured directly to the underside of the sock I; the cavity C is filledby a filler 20.

According to a modified method, the strip of filling material, e. g. ofleather, may be initially stitched to the platform flap, as, forinstance, by a single row of stitching, before the flap itself isstitched or otherwise attached to the upper.

Moreover, it may be found possible to dispense with the operationdepicted in Figure 4.

The platform flap may be made of any suitable material. It wouldpreferably be made of leather, although crepe rubber may be used.

The protuberant formation F providing the platform effect may extendeither merely around the forepart or around the arch or waist and theheel seat portion. or wholly around the improved shoe.

Moreover, depending on the type of shoe, the sock I may, instead ofterminating at the waist, extend throughout the length of the shoe-inwhich instance th hereinbefore described characteristic constructionwould extend right around the shoe instead of being confined to the forepart.

What I claim then is:

A slip-lasted shoe comprising upper material, a platform flap and arelatively thin sock-like layer, the lower edge of said upper material,one

5 edge of the platform flap and the peripheral edge of the sock-likelayer being in register, means securing the upper material and theplatform flap to the peripheral edge of the sock-like layer to form theupper component, further means securing the platform flap to the uppermaterial at a point remote from and parallel to the means securing theplatform flap and upper material to the peripheral edge of the sock-likelayer, a filling strip in facial contact with the platform flap, thelower edge of the filling strip being in registry with the lower edge ofthe upper material, the edge of the platform flap, and the peripheraledge of the sock-like layer, said platform flap being folded over saidfilling strip and terminating in an inturned portion disposed beneaththe lower edge of said upper material, the edge of the platform flap,the lower edge of the filling strip, and the peripheral edge of thesock-like layer, means securing said inturned portion beneath the uppercomponent whereby the filling strip and platform flap provide a verticalrelatively thin weltlike formation simulating a platform, and a soleapplied to the said component beneath the inturned portion of said flap.
